During normal breathing, the nasal cavity, pharyngeal cavity and respiratory tract all have humidification effect on inhaled gas. In clinical work, the gas inhaled by a patient with endotracheal intubation or tracheotomy directly enters the lower respiratory tract without upper respiratory tract humidification, viscous sputum is easy to generate due to lack of oral nasal humidification, and a considerable part of the sputum of the patient is easy to form sputum scab and is difficult to suck out, even the airway is blocked, bacterial infection and the like are caused, so that complications are easy to cause.

Airway humidification is therefore an important element of post-tracheotomy care. Through humidifying patient's air flue, can dilute the sputum to do benefit to the patient and discharge the sputum. One of the existing ways of airway humidification is to humidify the patient's airway with the aid of airway humidification tubes. One end of the airway humidifying tube is usually connected with the infusion apparatus, and the other end is connected with the autogenous cutting catheter, and liquid from the infusion apparatus is introduced into the airway, so that the airway of a patient is continuously humidified.
